You mean for the game to continuously crash at zero? That's not very common, but don't be caught up in gambler's fallacy also. Each run has it's own chances of going red, it's not affected by previous runs in a magical cosmos of chance. Not everything is related.

o_e_l_e_o () has also shown some important pointers about this topic and I wished the OP would actually come back to reply to some of these posts.
He has opened another thread here -
